Consider the following model of the goods market: Consumption is given by: Ct = C + c( Yt Tt ) Aggregatedemand: ADt =Ct +It +Gt. In equilibrium: Yt = ADt . Assume that Tt , It and Gt are exogenous and equal to constants: Tt = T , It = I , andGt =G. a. Find the (output) multiplier for an increase in government spending. b. Suppose Tt = Yt . Find the new government spending multiplier. Is it larger or smaller than the one derived in part a
